3C05 分子末端にニトロ基を持つ化合物のスメクチックA相の構造

抄録

This paper describes X-ray diffraction studies for smcctic A phases of 4-nitrophcnyl 4-(4-alkoxy- benzoyloxy)benzoates, 4-alkoxylphenyl 4-(4-nitrobenzoyloxy)benzoates, 4-(4-alkoxylbenzoyl- oxy)phenyl 4-nitrobenzoates, and 4-alkoxylphcnyl 4-nitrophcnyl tercphthalates. The layer spacings (d) are discussed in terms of thc molecular length (l) calculated by semi-empirical molecular orbital method and molecular arrangement.
